Hello My lap and desk top are almost alike yet the lap accepted the upgrade from 7 to 10 well; the desktop hangs randomly and has mouse issues. I even did a clean installation. I changed mice and all the remedial steps. I have done all the diagnostics I can even running the Dell dx program -clean. It seems the desktop does not have "guts" or drivers for 10. Dell does not support 10 drivers for this XPS 8300. Question, if I reinstalled Win 7 that the desktop came with and then updated all the BIOS etc. because Dell recognizes it as 7 not 10, then upgraded or imaged to 10 would that help or is that not advisable. Would it provide more support for 10 if 7 was beefed up? I hate to regress. All was well with 7,8, and 8.1.
